We just bought an old Dearborn model 14-42 hayrake. Greased it up and towing it around to check it out. It works but spins fast for a bit, then slow, then fast again. Towing it home I noticed the axle is a bit bent. Is this what's causing the irregular speed? Or something else? The wheels don't seem to be locking up and skidding on the ground.

Any ideas much appreciated.

And I thought I was old. 1953-1955. It looks like it has a two sets of universal joints. Whenever you have u-joints that are not straight in line, the u-joints speed up and slow down each revolution. Probably will not be noticeable in the field with a load against the rake.

Thanks, Mike10--that is definitely at least part of the phenomenon. The axle was also loose on one end and eventually got pulled back and wheels locked up. I fixed that, and it still seems like there is periodic resistance somewhere in the system--'course the worn-out hydraulics of my old 8N, and need to constantly adjust the height to keep the rake up off the ground may also be part of it. Think I'll have to get those hydraulics rebuilt before I think seriously about haying our 2-3 acres.
